Y+3=5(x+1). Solve for y

Answer:

See explanation below for all parts

Step-by-step explanation:

Your current slope (m) is -1/2 (the orange colored slope) so the "opposite" slope would be 2/1 or 2(the blue colored slope)

The answer for number 3 is y=2x+b.

For number 4, plug in the point values for x and y and solve for b. The point given is (-4,-5).

-5=2(-4)+b Now simplify

-5=-8+b then add 8 to both sides to isolate b

3=b or b=3

For number 9, you now know that m is 2 and b is 3

y=2x+3

Answer:   m = -8/9

Answer:

[tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]

Step-by-step explanation:

To solve an equation for one of its value

∵ A = 4πR²

→ Underline R

∴ A = 4πR²

→ Move 4π to the other side by dividing both sides by 4π

∵ [tex]\frac{A}{4\pi }=\frac{4\pi R^{2} }{4\pi }[/tex]

∴ [tex]\frac{A}{4\pi }=R^{2}[/tex]

→ To find R take √  for both sides

∴ [tex]\sqrt{\frac{A}{4\pi }}=\sqrt{R^{2} }[/tex]

→ You can simplify  [tex]\sqrt{\frac{1}{4}}[/tex] to [tex]\frac{1}{2}[/tex]

∴ [tex]\frac{1}{2} \sqrt{\frac{A}{\pi }}=R[/tex]

→ Switch the two sides

∴ [tex]R=\frac{1}{2} \sqrt{\frac{A}{\pi }}[/tex]

Answer:

Step-by-step explanation:

Given the expression [tex]\frac{720,800}{x} = 7.208[/tex], we are to find the value of with powers of 10.

From the equation:

[tex]\frac{720,800}{x} = 7.208[/tex]

cross multiply

[tex]720,800 = 7.208x\\7.208x = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{7.208x}{7.208} = \frac{720,800}{7.208} \\x = 100,000[/tex]

express x in powers of 10

[tex]x = 10 * 10 * 10 * 10* 10\\x = 10^5[/tex]

Similarly given the equation [tex]\frac{720,800}{y} = 72.08[/tex]

From the equation:

[tex]\frac{720,800}{x} = 72.08[/tex]

cross multiply

[tex]720,800 = 72.08x\\72.08x = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{72.08x}{72.08} = \frac{720,800}{72.08} \\x = 10,000[/tex]

express x in powers of 10

[tex]x = 10 * 10 * 10 * 10\\x = 10^4[/tex]

For the equation [tex]\frac{720,800}{z} = 720.8[/tex]

From the equation:

[tex]\frac{720,800}{z} = 720.8[/tex]

cross multiply

[tex]720,800 = 720.8z\\720.8z = 720,800[/tex]

divide both sides by 7.208

[tex]\frac{72.08z}{720.8} = \frac{720,800}{720.8} \\z = 1,000[/tex]

express x in powers of 10

[tex]z = 10 * 10 * 10\\z = 10^3[/tex]

The dividing 720,800 by 101010 successively four times in the parentheses results in 720.8

To complete the equations using powers of 101010:

720,800 ÷ (720,800 ÷ 720,800) = 7.208 = 7.208 equals 7.208

Explanation: Dividing 720,800 by 720,800, and then dividing the result by 720,800, yields 7.208.

720,800 ÷ (720,800 ÷ (720,800 ÷ 101010)) = 72.08 = 72.08 equals 72.08

Explanation: Dividing 720,800 by 101010, and then dividing 720,800 by the result, and finally dividing 720,800 by the new result, gives us 72.08.

720,800 ÷ (720,800 ÷ (720,800 ÷ (720,800 ÷ 101010))) = 720.8 = 720.8 equals 720.8

Answer:

c= e/d-ab/d

Step-by-step explanation:

The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

ab + cd = e

Simplify the equation for c, then we have

ab + cd = e

cd = e + ab

c = (e + ab) / d

The equation ab + cd = e is solved for the variable 'c' will be c = (e + ab) / d.

Answer:

[tex]V=80x-36x^2+4x^3[/tex]

Step-by-step explanation:

The volume of a box of dimensions a, b, c is:

V=abc

The box shown in the image has dimensions 8-2x, 10-2x, x, thus its volume is:

[tex]V=(8-2x)(10-2x)(x)[/tex]

Operating the first two brackets:

[tex]V=(80-16x-20x+4x^2)(x)[/tex]

Joining like terms:

[tex]V=(80-36x+4x^2)(x)[/tex]

Multiplying again:

[tex]V=80x-36x^2+4x^3[/tex]

The volume of the box is

[tex]\boxed{V=80x-36x^2+4x^3}[/tex]

Answer:

Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.

Step-by-step explanation:

Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:

[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]

Donde:

[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.

[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.

[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.

Entonces calculamos el tiempo correspondiente a cada amigo:

Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 7.5\,min[/tex]

Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 24\,min[/tex]

Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])

[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]

[tex]\Delta t = 28.5\,min[/tex]

Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.

Given the expression :

Total cost after tax = 0.08(50h) + 50h

a. What part of the expression represents the amount of tax Deborah has to pay? Explain

0.08(50h) represents Tha amount of tax Deborah has to pay. This can be interpreted as :

Recall;

Tax amount = tax rate * cost

Cost of repair = 50h = 50 per hour

Tax rate = 0.08 = 8% of the total cost;

Hence; 0.08(50h) = tax Deborah has to pay.

What would the expression be if the company charged Deborah $45 per hour to repair the computer (plus tax)?

If she was charged $45 per hour plus tax. Expression becomes ;

Total cost after tax = 0.08(45h) + 45h

= 3.6h + 45h

= 48.6h
